Documents Birute Galdikas-Brindamour's research project on the behavior of wild orangutans in Borneo, focusing on her attempts to return confiscated juvenile organutans to the rain forest. Habituation of a wild adult male orangutan, after weeks of following it through the forest, provides her first data on orangutan behavior

There's good reason Biruté took large, unproductive, stretches of inactivity after publishing her first (only) research, effectively marooning all of findings and paper(s) post-1970's (Other than Focusing her resources on For-Profit Education/Fundraising) She'd gained to much notoriety & popularity to ever be granted the freedom to work entirely un-monitored, free of verification or due diligence Albeit, she did publish a bit more after submitting her initial (claim to fame to fluke) data, but A L L of that later work turned out to be retreading her initial findings, regurgitating anything and everything from her earlier, 1970's submission (until her colleagues pointed this out publicly, at which point she attacked them in the press, abandoned any further studies and promptly went about selling eco-tourism packages (advertising tourists could "research" with her!) Also, she couldn't risk letting anyone else finding out the truth about her research (you'll find no better Reason explaining the aforementioned selected clip + quote @22'30:)
BIRUTE GALDIKAS NEVER COULD TRACK OR RESEARCH "WILD" ORANGUTANS; 100% OF HER DATA / RESEARCH / WORK WAS CULLED FROM OBSERVING THE CAPTIVE (non-native) ORANG UTANS THROUGHOUT HER CAMP / RESIDENCE.
Even her ex husband verified as much.
She's a charlatan, folks!
Don't take my word for it, just read any of Linda Spalding's literature regarding her brief time w Birute.
